Aimed at the surfer looking to leverage technology to assist in navigating the gnarliest waves, Casio presents the G-Shock G-Lide GWX-8900B-7DR with a tide/moon graph display. Going a step further from its predecessors, this display features tidal movements for the top 100 surf locations around the world, with an additional 49 unused slots available for the user to affix their favorite destinations. Furthermore, this G-Lide offers a shockproof and 200m water-resistant casing, solar-powered battery, full auto super Illuminator LED, and the usual G-Shock workings. Available in all black or black and white, this cutting edge timepiece will release this August at select stockists.
